Description of Issue

Every year a new Roon update drops recognition of my Yaggy. I have tried all the restarts and downloads of new (254) software, but this time it just will not work.

Nucleus will not provide signal to Yaggy. USB connection appears solid. The Yggy sees the
power from the Nucleus. The Nuc will recognize my CD codec if plugged into a cheap phono to USB converter.

I am considering dumping my whole rig without replacement. I have just about had all the software nonsense I can take.
